To provide a deformed pipe having no local back draft and gap at the connected part thereof to a straight pipe.
This deformed pipe for pipe bottom connection in which the centers of a main pipe and a branch pipe are not aligned with each other and the bottoms thereof are aligned with each other is used to join the straight pipes to be connected (a suction pipe and a collecting pipe) thereto when the diameters of the straight pipes are different from each other. The deformed pipe can be used for T-pipes, Y-pipes, and L-pipes. Usually, the deformed pipe is used while the pipes to be connected are aligned with each other on the lower bottoms. However, the deformed pipe can be used reversely while the pipes to be connected are aligned with each other on the upper bottoms. The deformed pipe can be manufactured in the form of an earth-friendly unglazed clay pipe.
